Continuous production of acrylamide byBrevibacterium sp. immobilized in a dual hollow fiber bioreactor

Summary Acrylamide was continuously produced from acrylonitrile usingBrevibacterium sp. CHl grown and immobilized in a dual hollow fiber bioreactor of 8.0 cm³. The biomass reached as high as 200 gm/L of the space available for the cell growth. The volumetric productivity of the reactor was 88 gm/L. h and the conversion of acrylonitrile varied with acrylonitrile concentration, pH and feed rate.
